This application is a divisional of U.S. application Ser. No. 10/444,946, filed May 22, 2003, which claims the benefit of U.S. Provisional Application No. 60/441,065, filed Jan. 17, 2003, and U.S. Provisional Application No. 60/383,050, filed May 23, 2002, which are hereby incorporated by reference.

BACKGROUND OF THE INVENTION

Extracellular calcium ion concentration is involved in a variety of biological processes, such as blood clotting, nerve and muscle excitability and bone formation (Cell Calcium 11: 319, 1990). Calcium ion receptors, which are present on the membranes of various cells in the body, such as parathyroid and kidney cells (Nature 366: 574, 1993; J. Bone Miner. Res. 9, Supple. 1, s282, 1994; J. Bone Miner. Res. 9, Supple. 1, s409, 1994; Endocrinology 136: 5202, 1995), are important to the regulation of the extracellular calcium ion concentration. For example, concentration of extracellular calcium ion regulates the bone resorption by osteoclasts (Bioscience Reports 10: 493, 1990), secretion of parathyroid hormone (PTH) from parathyroid cells and secretion of calcitonin from C-cells (Cell Calcium 11: 323, 1990). Parathyroid hormone (PTH) is an important factor in regulating extracellular calcium ion concentration. Secretion of PTH increases extracellular calcium ion concentration by acting on various cells, such as bone and kidney cells, and the extracellular calcium ion concentration reciprocally inhibits the secretion of PTH by acting on parathyroid cells.

Several classes of calcimimetic compounds have been disclosed for regulating extracellular calcium ion concentration, particularly for reducing or inhibiting secretion of PTH. For example, U.S. Pat. Nos. 6,011,068 and 5,981,599 disclose arylalkylamines that are calcium receptor active molecules. EP 933354; WO 0021910, WO 96/12697; WO 95/11221; WO 94/18959; WO 93/04373; Endocrinology 128: 3047, 1991; Biochem. Biophys. Res. Commun. 167: 807, 1990; J. Bone Miner. Res. 5: 581, 1990; and Nemeth et al., “Calcium-binding Proteins in Health and Disease,” Academix Press, Inc., pp. 33-35 (1987) disclose various agents that interact with calcium receptors.

Dauban et al., Bioorg. Med. Chem. Let. 10: 2001-4, 2000, disclose various N1-arylsulfonyl-N2-(1-aryl)ethyl-3-phenylpropane-1,2-diamine compounds as calcimimetics acting on the calcium sensing receptor.

Oikawa et al., in U.S. Pat. No. 6,403,832, and publication No. US2002/143212, describes aryl amine compounds useful as chiral intermediates in the synthesis of optically active propionic acid derivatives. Chassot et al., U.S. Pat. No. 6,436,152, describes arylalkylamine compounds useful as hair dye precursor compounds.

Bös et al., U.S. Pat. No. 6,407,111, describes phenyl substituted pyridine and benzene derivates that are antagonistic to the NK-1 receptor.

Compounds of the present invention can possess one or more asymmetric carbon atoms and are thus capable of existing in the form of optical isomers as well as in the form of racemic or non-racemic mixtures thereof. The optical isomers can be obtained by resolution of the racemic mixtures according to conventional processes, e.g., by formation of diastereoisomeric salts, by treatment with an optically active acid or base. Examples of appropriate acids are tartaric, diacetyltartaric, dibenzoyltartaric, ditoluoyltartaric, and camphorsulfonic acid and then separation of the mixture of diastereoisomers by crystallization followed by liberation of the optically active bases from these salts. A different process for separation of optical isomers involves the use of a chiral chromatography column optimally chosen to maximize the separation of the enantiomers. Still another available method involves synthesis of covalent diastereoisomeric molecules by reacting compounds of the invention with an optically pure acid in an activated form or an optically pure isocyanate. The synthesized diastereoisomers can be separated by conventional means such as chromatography, distillation, crystallization or sublimation, and then hydrolyzed to deliver the enantiomerically pure compound. The optically active compounds of the invention can likewise be obtained by using active starting materials. These isomers may be in the form of a free acid, a free base, an ester or a salt. The (R) isomer is generally preferred.

Likewise, the compounds of this invention may exist as isomers, that is compounds of the same molecular formula but in which the atoms, relative to one another, are arranged differently. In particular, the alkylene substituents of the compounds of this invention, are normally and preferably arranged and inserted into the molecules as indicated in the definitions for each of these groups, being read from left to right. However, in certain cases, one skilled in the art will appreciate that it is possible to prepare compounds of this invention in which these substituents are reversed in orientation relative to the other atoms in the molecule. That is, the substituent to be inserted may be the same as that noted above except that it is inserted into the molecule in the reverse orientation. One skilled in the art will appreciate that these isomeric forms of the compounds of this invention are to be construed as encompassed within the scope of the present invention.

The compounds of the present invention can be used in the form of pharmaceutically acceptable salts derived from inorganic or organic acids. The salts include, but are not limited to, the following: acetate, adipate, alginate, citrate, aspartate, benzoate, benzenesulfonate, bisulfate, butyrate, camphorate, camphorsulfonate, digluconate, cyclopentanepropionate, dodecylsulfate, ethanesulfonate, glucoheptanoate, glycerophosphate, hemisulfate, heptanoate, hexanoate, fumarate, hydrochloride, hydrobromide, hydroiodide, 2-hyroxyethanesulfonate, lactate, maleate, mandelate, methansulfonate, nicotinate, 2-naphthalenesulfonate, oxalate, palmoate, pectinate, persulfate, 2-phenylpropionate, picrate, pivalate, propionate, salicylate, succinate, sulfate, tartrate, thiocyanate, tosylate, mesylate, and undecanoate. Other examples include salts with alkali metals or alkaline earth metals, such as sodium, potassium, calcium or magnesium or with organic bases. When compounds of the invention include an acidic function such as a carboxy group, then suitable pharmaceutically acceptable cation pairs for the carboxy group are well known to those skilled in the art and include alkaline, alkaline earth, ammonium, quaternary ammonium cations and the like. For additional examples of “pharmacologically acceptable salts,” see infra and Berge et al., J. Pharm. Sci. 66: 1 (1977).

Also, the basic nitrogen-containing groups can be quaternized with such agents as lower alkyl halides, such as methyl, ethyl, propyl, and butyl chloride, bromides and iodides; dialkyl sulfates like dimethyl, diethyl, dibutyl, and diamyl sulfates, long chain halides such as decyl, lauryl, myristyl and stearyl chlorides, bromides and iodides, aralkyl halides like benzyl and phenethyl bromides, and others. Water or oil-soluble or dispersible products are thereby obtained.

Also encompassed in the scope of the present invention are pharmaceutically acceptable esters of a carboxylic acid or hydroxyl containing group, including a metabolically labile ester or a prodrug form of a compound of this invention. A metabolically labile ester is one which may produce, for example, an increase in blood levels and prolong the efficacy of the corresponding non-esterified form of the compound. A prodrug form is one which is not in an active form of the molecule as administered but which becomes therapeutically active after some in vivo activity or biotransformation, such as metabolism, for example, enzymatic or hydrolytic cleavage. For a general discussion of prodrugs involving esters see Svensson and Tunek Drug Metabolism Reviews 165 (1988) and Bundgaard Design of Prodrugs, Elsevier (1985). Examples of a masked carboxylate anion include a variety of esters, such as alkyl (for example, methyl, ethyl), cycloalkyl (for example, cyclohexyl), aralkyl (for example, benzyl, p-methoxybenzyl), and alkylcarbonyloxyalkyl (for example, pivaloyloxymethyl). Amines have been masked as arylcarbonyloxymethyl substituted derivatives which are cleaved by esterases in vivo releasing the free drug and formaldehyde (Bungaard J. Med. Chem. 2503 (1989)). Also, drugs containing an acidic NH group, such as imidazole, imide, indole and the like, have been masked with N-acyloxymethyl groups (Bundgaard Design of Prodrugs, Elsevier (1985)). Hydroxy groups have been masked as esters and ethers. EP 039,051 (Sloan and Little, Apr. 11, 1981) discloses Mannich-base hydroxamic acid prodrugs, their preparation and use. Esters of a compound of this invention, may include, for example, the methyl, ethyl, propyl, and butyl esters, as well as other suitable esters formed between an acidic moiety and a hydroxyl containing moiety. Metabolically labile esters, may include, for example, methoxymethyl, ethoxymethyl, iso-propoxymethyl, α-methoxyethyl, groups such as α-((C₁-C₄)alkyloxy)ethyl; for example, methoxyethyl, ethoxyethyl, propoxyethyl, iso-propoxyethyl, etc.; 2-oxo-1,3-dioxolen-4-ylmethyl groups, such as 5-methyl-2-oxo-1,3,dioxolen-4-ylmethyl, etc.; C₁-C₃ alkylthiomethyl groups, for example, methylthiomethyl, ethylthiomethyl, isopropylthiomethyl, etc.; acyloxymethyl groups, for example, pivaloyloxymethyl, α-acetoxymethyl, etc.; ethoxycarbonyl-1-methyl; or α-acyloxy-α-substituted methyl groups, for example α-acetoxyethyl.

Further, the compounds of the invention may exist as crystalline solids which can be crystallized from common solvents such as ethanol, N,N-dimethyl-formamide, water, or the like. Thus, crystalline forms of the compounds of the invention may exist as solvates and/or hydrates of the parent compounds or their pharmaceutically acceptable salts. All of such forms likewise are to be construed as falling within the scope of the invention.

“Leaving group” generally refers to groups readily displaceable by a nucleophile, such as an amine, a thiol or an alcohol nucleophile. Such leaving groups are well known in the art. Examples of such leaving groups include, but are not limited to, N-hydroxysuccinimide, N-hydroxybenzotriazole, halides, triflates, tosylates and the like. Preferred leaving groups are indicated herein where appropriate.

“Protecting group” generally refers to groups well known in the art which are used to prevent selected reactive groups, such as carboxy, amino, hydroxy, mercapto and the like, from undergoing undesired reactions, such as nucleophilic, electrophilic, oxidation, reduction and the like. Preferred protecting groups are indicated herein where appropriate. Examples of amino protecting groups include, but are not limited to, aralkyl, substituted aralkyl, cycloalkenylalkyl and substituted cycloalkenyl alkyl, allyl, substituted allyl, acyl, alkoxycarbonyl, aralkoxycarbonyl, silyl and the like. Examples of aralkyl include, but are not limited to, benzyl, ortho-methylbenzyl, trityl and benzhydryl, which can be optionally substituted with halogen, alkyl, alkoxy, hydroxy, nitro, acylamino, acyl and the like, and salts, such as phosphonium and ammonium salts. Examples of aryl groups include phenyl, naphthyl, indanyl, anthracenyl, 9-(9-phenylfluorenyl), phenanthrenyl, durenyl and the like. Examples of cycloalkenylalkyl or substituted cycloalkylenylalkyl radicals, preferably have 6-10 carbon atoms, include, but are not limited to, cyclohexenyl methyl and the like. Suitable acyl, alkoxycarbonyl and aralkoxycarbonyl groups include benzyloxycarbonyl, t-butoxycarbonyl, iso-butoxycarbonyl, benzoyl, substituted benzoyl, butyryl, acetyl, tri-fluoroacetyl, tri-chloro acetyl, phthaloyl and the like. A mixture of protecting groups can be used to protect the same amino group, such as a primary amino group can be protected by both an aralkyl group and an aralkoxycarbonyl group. Amino protecting groups can also form a heterocyclic ring with the nitrogen to which they are attached, for example, 1,2-bis(methylene)benzene, phthalimidyl, succinimidyl, maleimidyl and the like and where these heterocyclic groups can further include adjoining aryl and cycloalkyl rings. In addition, the heterocyclic groups can be mono-, di- or tri-substituted, such as nitrophthalimidyl. Amino groups may also be protected against undesired reactions, such as oxidation, through the formation of an addition salt, such as hydrochloride, toluenesulfonic acid, trifluoroacetic acid and the like. Many of the amino protecting groups are also suitable for protecting carboxy, hydroxy and mercapto groups. For example, aralkyl groups. Alkyl groups are also suitable groups for protecting hydroxy and mercapto groups, such as tert-butyl.

Silyl protecting groups are silicon atoms optionally substituted by one or more alkyl, aryl and aralkyl groups. Suitable silyl protecting groups include, but are not limited to, trimethylsilyl, triethylsilyl, tri-isopropylsilyl, tert-butyldimethylsilyl, dimethylphenylsilyl, 1,2-bis(dimethylsilyl)benzene, 1,2-bis(dimethylsilyl)ethane and diphenylmethylsilyl. Silylation of an amino groups provide mono- or di-silylamino groups. Silylation of aminoalcohol compounds can lead to a N,N,O-tri-silyl derivative. Removal of the silyl function from a silyl ether function is readily accomplished by treatment with, for example, a metal hydroxide or ammonium fluoride reagent, either as a discrete reaction step or in situ during a reaction with the alcohol group. Suitable silylating agents are, for example, trimethylsilyl chloride, tert-butyl-dimethylsilyl chloride, phenyldimethylsilyl chloride, diphenylmethyl silyl chloride or their combination products with imidazole or DMF. Methods for silylation of amines and removal of silyl protecting groups are well known to those skilled in the art. Methods of preparation of these amine derivatives from corresponding amino acids, amino acid amides or amino acid esters are also well known to those skilled in the art of organic chemistry including amino acid/amino acid ester or aminoalcohol chemistry.

Protecting groups are removed under conditions which will not affect the remaining portion of the molecule. These methods are well known in the art and include acid hydrolysis, hydrogenolysis and the like. A preferred method involves removal of a protecting group, such as removal of a benzyloxycarbonyl group by hydrogenolysis utilizing palladium on carbon in a suitable solvent system such as an alcohol, acetic acid, and the like or mixtures thereof. A t-butoxycarbonyl protecting group can be removed utilizing an inorganic or organic acid, such as HCl or trifluoroacetic acid, in a suitable solvent system, such as dioxane or methylene chloride. The resulting amino salt can readily be neutralized to yield the free amine. Carboxy protecting group, such as methyl, ethyl, benzyl, tert-butyl, 4-methoxyphenylmethyl and the like, can be removed under hydrolysis and hydrogenolysis conditions well known to those skilled in the art.

It should be noted that compounds of the invention may contain groups that may exist in tautomeric forms, such as cyclic and acyclic amidine and guanidine groups, heteroatom substituted heteroaryl groups (Y′═O, S, NR), and the like, which are illustrated in the following examples:

and though one form is named, described, displayed and/or claimed herein, all the tautomeric forms are intended to be inherently included in such name, description, display and/or claim.

A “derivative” of a compound of the invention includes salts, isomers, enantiomers, prodrugs, and metabolites of the compound.

Prodrugs of the compounds of this invention are also contemplated by this invention. A prodrug is an active or inactive compound that is modified chemically through in vivo physiological action, such as hydrolysis, metabolism and the like, into a compound of this invention following administration of the prodrug to a patient. The suitability and techniques involved in making and using prodrugs are well known by those skilled in the art. For a general discussion of prodrugs involving esters see Svensson and Tunek, Drug Metabolism Reviews 165 (1988) and Bundgaard, Design of Prodrugs, Elsevier (1985). One method of preparing a prodrug of a compound is by masking one or more potentially reactive groups on the compound, such as carboxylates, hydroxy groups, and amines. Examples of a masked carboxylate anion include a variety of esters, such as alkyl (for example, methyl, ethyl), cycloalkyl (for example, cyclohexyl), aralkyl (for example, benzyl, p-methoxybenzyl), and alkylcarbonyloxyalkyl (for example, pivaloyloxymethyl). Amines have been masked as arylcarbonyloxymethyl substituted derivatives which are cleaved by esterases in vivo releasing the free drug and formaldehyde (Bungaard, J. Med. Chem. 2503 (1989)). Also, drugs containing an acidic NH group, such as imidazole, imide, indole and the like, have been masked with N-acyloxymethyl groups (Bundgaard, Design of Prodrugs, Elsevier (1985)). Hydroxy groups have been masked as esters and ethers. EP 039,051 (Sloan and Little, Apr. 11, 1981) discloses Mannich-base hydroxamic acid prodrugs, their preparation and use.

Experimental

General:

Method A: the aldehyde (1.6 mmol) is dissolved in methanol (5 mL) and the amine (1.9 mmol) is added. The reaction is shaken for 24 hours or until imine formation is complete (as monitored by LCMS), then solid supported borohydride is added (prepared according to Kabalka, G. W.; Wadgaonkar, P.

Dichloromethane (ca 3 mL) is then added followed by Wang-aldehyde resin (4-benzyloxybenzaldehyde, polymer-bound; ca 1.25 mmol/g; 0.6 mmol) and the mixture is shaken for further 24 hours. The resins are filtered off and the solvents are evaporated under reduced pressure, to afford an oil which is purified by column chromatography (usually Hexane/AcOEt 7/3 or DCM/MeOH 95/5). The free-base oil is then treated with 1.5-2.5 1N HCl in diethyl ether and the solvents are evaporated under reduced pressure to afford the mono or bis-HCl salt.

Method B: the aldehyde (1.6 mmol) is dissolved in methanol (5 mL) and the amine (1.9 mmol) is added. The reaction is heated to reflux for 10 minutes then left to cool overnight until imine formation is complete (as monitored by LCMS). Solid supported cyanoborohydride is added (prepared according to Sande, A. R.; Jagadale, M. H.; Mane, R. B.; Salunkhe, M. M.; Tetrahedron Lett. (1984), 25 (32), 3501-4) (ca 2.5 mmol/g; 3.1 mmol) and the mixture is heated at 50 C for 15 hours or until reduction is complete (as monitored by LCMS).

Dichloromethane (ca 3 mL) is then added followed by Wang-aldehyde resin (4-benzyloxybenzaldehyde, polymer-bound; ca 1.25 mmol/g; 0.6 mmol) and the mixture is shaken for further 24 hours. The resins are filtered off and the solvents are evaporated under reduced pressure, to afford an oil which is purified by column chromatography (usually Hexane/AcOEt 7/3 or DCM/MeOH 95/5). The free-base oil is then treated with 1.5-2.5 1N HCl in diethyl ether and the solvents are evaporated under reduced pressure to afford the mono or bis-HCl salt.

Method C: The aldehyde is (1.6 mmol) is dissolved in 1,2-dichloroethane (12 mL) and the amine (1.9 mmol) is added, followed by acetic acid (0.09 mL, 1.6 mmol) and finally sodium triacetoxyborohydride (500 mg, 2.4 mmol). The mixture is stirred overnight or until complete by TLC; upon reaction completion, the mixture is diluted with ethyl acetate, washed with saturated NaHCO₃ then with saturated brine, and finally dried over sodium sulphate. The solvents are evaporated under reduced pressure, to afford an oil which is purified by column chromatography on silica gel (usually Hexane/AcOEt 7/3 or DCM/MeOH 95/5). The free-base oil is then treated with 1.5-2.5 equivalents 1N HCl in diethyl ether and the solvents are evaporated under reduced pressure to afford the mono or bis-HCl salt.

Method D: Compounds wherein both R³ and R⁴ are other than hydrogen can be prepared by combining an appropriately substituted phenylacetic acid with a strong base such as lithium diisopropylamide or the like at a temperature between −78 and 20° C. to yield a red dianion. The dianion is then reacted with an alkylating agent of formula R³-Z, wherein Z is a halide, a sulfonate, or other suitable leaving group to provide an R³ substituted compound. Treatment of the compound thus obtained with a strong base such as lithium diisopropylamide or the like at a temperature between −78 and 20° C. yields a second red dianion, which is reacted with an alkylating agent of formula R⁴-Z, wherein Z is a halide, a sulfonate, or other suitable leaving group to yield the R³, R⁴ disubstituted compound. Treatment of the resultant carboxylic acid with diphenylphosphoryl azide in a refluxing solvent (for example toluene, benzene, chlorobenzene, 1,4-dioxane or the like), followed by aqueous workup yields the R³ substituted R⁴amine. Reductive coupling of the amine with an aldehyde or ketone according to Method C affords the final product.

Method E: Compounds wherein only one of R³ and R⁴ is hydrogen can be prepared by reacting the α-monosubstituted carboxylic acid obtained by reacting an appropriately substituted phenylacetic acid with a strong base such as lithium diisopropylamide and then with an alkylating agent of formula R³-Z as described above with diphenylphosphoryl azide in a refluxing solvent such as, for example, toluene, benzene, chlorobenzene, 1,4-dioxane, etc. followed by an aqueous workup to yield a mono-α-substituted amine. This amine can then be reacted with an aldehyde or ketone according to Method C to obtain the final product.

Biological Activity

The activities of the compounds of the present invention on calcium receptors were measured. In one embodiment, the measurement was performed in accordance with the method described in Example 4 of Nemeth et al., PCT/US95/13704 (International Publication No. WO96/12697) herein incorporated by reference.

A 4.0-kb NotI-HindIII fragment of the human parathyroid cell Ca²⁺ receptor (hPCaR) cDNA was subcloned into the mammalian expression vector pCEP4 (Invitrogen) containing the hygromycin-resistant gene as a selectable marker. This plasmid was transfected into HEK 293 cells by calcium phosphate precipitation. Transfected cells were grown in Dulbecco's modified Eagle's medium containing 10% fetal bovine serum and hygromycin (200 μg/mL). Hygromycin-resistant colonies were subcloned and assayed for hPCaR mRNA by solution hybridization using a ³²P-labeled RNA probe complementary to the (4.0 kb) hPCaR sequence (Garrett, et al., J. Biol. Chem. 270, 12919-12925 (1995)). Clone 7 was used to assess the effects of compounds on [Ca²⁺]_(i). This stably transfected cell line is termed HEK 293 4.0-7. For measurements of [Ca²⁺]_(i), the cells were recovered from tissue culture flasks by brief treatment with 0,02% EDTA and then washed and resuspended in PCB containing 1 mM CaCl₂ and 0.1% Bovine Serum Albumin (“BSA”). The cells were loaded with fluo-3 by incubation for 30 min at 37° C., with parathyroid cell buffer (126 mM NaCl, 4 mM KCl, 1 mM MgSO₄, 0.7 mM K₂HPO₄/KH₂PO₄, 20 mM HEPES.NaOH (pH 7.45)) containing 0.5% BSA in 1 mM CaCl₂ and 2 μM fluo-3 acetoxymethyl ester. The cells were subsequently washed, each test compound was added to the cells and the fluorescence was recorded by using excitation and emission wavelengths of 485 and 530 nm, respectively.

The following compounds of the invention were tested according to the procedure described above and found to have an EC50 of 10 μM or less:

For the treatment of bone disorders, such as osteoporosis, excessive secretion of PTH, such as hyperparathyroidism, and the like, the compounds of the present invention may be administered orally, parentally, by inhalation spray, rectally, or topically in dosage unit formulations containing conventional pharmaceutically acceptable carriers, adjuvants, and vehicles. The term “parenteral” as used herein includes, subcutaneous, intravenous, intramuscular, intrasternal, infusion techniques or intraperitoneally.

Treatment of diseases and disorders herein is intended to also include the prophylactic administration of a compound of the invention, a pharmaceutical salt thereof, or a pharmaceutical composition of either to a subject (i.e., an animal, preferably a mammal, most preferably a human) believed to be in need of preventative treatment, such as, for example, pain, inflammation and the like.

The dosage regimen for treating the disclosed diseases with the compounds of this invention and/or compositions of this invention is based on a variety of factors, including the type of disease, the age, weight, sex, medical condition of the patient, the severity of the condition, the route of administration, and the particular compound employed. Thus, the dosage regimen may vary widely, but can be determined routinely using standard methods. Dosage levels of the order from about 0.01 mg to 30 mg per kilogram of body weight per day, preferably from about 0.1 mg to 10 mg/kg, more preferably from about 0.25 mg to 1 mg/kg are useful for all methods of use disclosed herein.

The pharmaceutically active compounds of this invention can be processed in accordance with conventional methods of pharmacy to produce medicinal agents for administration to patients, including humans and other mammals.

For oral administration, the pharmaceutical composition may be in the form of, for example, a capsule, a tablet, a suspension, or liquid. The pharmaceutical composition is preferably made in the form of a dosage unit containing a given amount of the active ingredient. For example, these may contain an amount of active ingredient from about 1 to 2000 mg, preferably from about 1 to 500 mg, more preferably from about 5 to 150 mg. A suitable daily dose for a human or other mammal may vary widely depending on the condition of the patient and other factors, but, once again, can be determined using routine methods.

The active ingredient may also be administered by injection as a composition with suitable carriers including saline, dextrose, or water. The daily parenteral dosage regimen will be from about 0.1 to about 30 mg/kg of total body weight, preferably from about 0.1 to about 10 mg/kg, and more preferably from about 0.25 mg to 1 mg/kg.

Injectable preparations, such as sterile injectable aqueous or oleaginous suspensions, may be formulated according to the known are using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed, including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.

Suppositories for rectal administration of the drug can be prepared by mixing the drug with a suitable non-irritating excipient such as cocoa butter and polyethylene glycols that are solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum and release the drug.

A suitable topical dose of active ingredient of a compound of the invention is 0.1 mg to 150 mg administered one to four, preferably one or two times daily. For topical administration, the active ingredient may comprise from 0.001% to 10% w/w, e.g., from 1% to 2% by weight of the formulation, although it may comprise as much as 10% w/w, but preferably not more than 5% w/w, and more preferably from 0.1% to 1% w/w of the formulation.

Formulations suitable for topical administration include liquid or semi-liquid preparations suitable for penetration through the skin (e.g., liniments, lotions, ointments, creams, or pastes) and drops suitable for administration to the eye, ear, or nose.

For administration, the compounds of this invention are ordinarily combined with one or more adjuvants appropriate for the indicated route of administration. The compounds may be admixed with lactose, sucrose, starch powder, cellulose esters of alkanoic acids, stearic acid, talc, magnesium stearate, magnesium oxide, sodium and calcium salts of phosphoric and sulphuric acids, acacia, gelatin, sodium alginate, polyvinyl-pyrrolidine, and/or polyvinyl alcohol, and tableted or encapsulated for conventional administration. Alternatively, the compounds of this invention may be dissolved in saline, water, polyethylene glycol, propylene glycol, ethanol, corn oil, peanut oil, cottonseed oil, sesame oil, tragacanth gum, and/or various buffers. Other adjuvants and modes of administration are well known in the pharmaceutical art. The carrier or diluent may include time delay material, such as glyceryl monostearate or glyceryl distearate alone or with a wax, or other materials well known in the art.

The pharmaceutical compositions may be made up in a solid form (including granules, powders or suppositories) or in a liquid form (e.g., solutions, suspensions, or emulsions). The pharmaceutical compositions may be subjected to conventional pharmaceutical operations such as sterilization and/or may contain conventional adjuvants, such as preservatives, stabilizers, wetting agents, emulsifiers, buffers etc.

Solid dosage forms for oral administration may include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound may be admixed with at least one inert diluent such as sucrose, lactose, or starch.

Such dosage forms may also comprise, as in normal practice, additional substances other than inert diluents, e.g., lubricating agents such as magnesium stearate. In the case of capsules, tablets, and pills, the dosage forms may also comprise buffering agents. Tablets and pills can additionally be prepared with enteric coatings.

Liquid dosage forms for oral administration may include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs containing inert diluents commonly used in the art, such as water. Such compositions may also comprise adjuvants, such as wetting, sweetening, flavoring, and perfuming agents.

While the compounds of the invention can be administered as the sole active pharmaceutical agent, they can also be used in combination with one or more compounds of the invention or other agents. When administered as a combination, the therapeutic agents can be formulated as separate compositions that are given at the same time or different times, or the therapeutic agents can be given as a single composition.

The foregoing is merely illustrative of the invention and is not intended to limit the invention to the disclosed compounds. Variations and changes which are obvious to one skilled in the art are intended to be within the scope and nature of the invention which are defined in the appended claims.
